Windows and doors in Greenloaning
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Greenloaning, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Greenloaning is about 9 miles north of Stirling, in Stirling. Anywhere in FK15, we cover window mastic for homes and businesses. Across Stirling, we cover 55 places, and Greenloaning is one of them. There’s also a page for Glasgow, roughly 31 miles from Greenloaning.

How we handle window mastic in Greenloaning
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on window sills, composite doors and timber windows & doors, and common reasons people get in touch are old mastic that has gone black or come away and untidy mastic left by window fitters.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Each job carries a 12-month guarantee, large or small.

What else we do in Greenloaning
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep paint and stain on wooden frames in good order
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
- Do not paint over the silicone
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Surface by surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall and tooled smooth.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
What we can’t put right
Sealant is not the answer to every problem, and we’ll tell you before we start. It won’t solve:
- A failed sealed unit that has misted up
- Worn gaskets, brush seals or a door that has dropped
- A frame that has rotted at the joint
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

What guarantee comes with window mastic in Greenloaning?
All our work, in Greenloaning and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you do upstairs windows?
Yes, in most cases. Access is planned before any work starts.
What does window mastic cost?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can I paint over the new sealant?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.

How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Clear the area around the work
- Keep children and pets away from the work area
- Let us know about parking restrictions

Related advice
Do you need window mastic in Greenloaning?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
The most common problems we see are:
- Rushed sealant from a window installation
- Damp patches on the reveal after heavy rain
- Black, perished sealant on frames
- Draughts coming in around windows and doors
In the older streets around Greenloaning Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
